Is it always better to select as few remedies as possible?

The normal guideline is to try to use no more than six or seven at a time, since experience has shown that more than this number is not usually necessary if a little thought goes into the selection process. Taking more remedies than are actually needed means that the focus is lost, and the ones that are necessary will not work as well or quickly as they might otherwise have done.

However, it is not true that three remedies are always better than four, or that the ideal selection is a single remedy: if six (or eight, or even nine) remedies really are necessary, that is how many you should take.
